Ancelotti is also without playmaker Thiago Alcantara and new signing James Rodriguez, who is on a two-year loan deal from Real Madrid, after picking up injuries in pre-season.

Defenders Jerome Boateng and Javi Martinez are out with leg knocks.

"We'll see which players will be available on Friday," Ancelotti said.

There is some positive news.

New club captain Manuel Neuer could play, but a decision will only be made on Thursday after the goalkeeper only recently returned after foot surgery.

"Since he is our captain, it would be a bonus," chairman Karl-Heinz Rummenigge said.

Luckily for Bayern, their away match at Werder Bremen the following weekend comes just before the international break.

"We'll be able to integrate all our players then," Ancelotti added, but new signings Niklas Suele and Sebastian Rudy are likely to be with Germany, while record-signing Corentin Tolisso is set to be with France.
